SPECFICATION forming' part of Letters Patent No. 405,730, dated .Inne25, 1889. Application filed April 6, 1889. Serial No. 306,156. (Nomodel.)

To all w/"z'om it may concern:

Be it known that I, CHARLES A. GILDE- MEYER, of Haddonfield, county ofCamden, State of New Jersey, have invented a new and useful ImprovedSeal, of which the following is a true and exact description, referencebeing had to the accompanying drawings, which form a part of thisspecification.

My invention relates to the construction of seals such as are used toprevent the opening of freight-cars without detection, and for similaruses; and my object is to provide a seal of this kind which shall besecure against attempts to open it without leaving clea-rly noticeabletraces of the attempt.

My invention will be best understood after a description of the drawingsby which it is illustrated; and the novel features which I desire toprotect are clearly pointed out in the claims.

In the drawings, Figure l is a perspective 4 view of my improved seal asit appears in use. Fig. 2 shows in perspective the different parts of myseal in the condition they are in before being put and secured together.Fig. 3 is a central cross-section through the seal, as shown in Fig. 1;and Fig. 4 illustrates a modification of my device.

A is a metallic plate consisting of a plain face a, with turned-np edges(t'. 'This edge or flange a' is cut away at one point (L2 to permit theinsertion of the suspending-wire B, as will be described, and preferablythe rim is also cut away or the corner perforated on the opposite side,so as to permit the ends of the wire B to extend outside of the rim a'.In Figs. 1 and 2 this opening is indicated at a* as being formed in thecorner of the plate A, the alternative construction in which the rim iscut away, as at (bcing iudicated by the dotted lines at (L5.

It is desirable that the portions of the wire B which pass through theflanged plate A should lie substantially 'Ilush with the surface of itsflat portion a, and I therefore prefer to form one or more grooves forthe arms of the wire B to rest in. lVhere a thick cast plate A is used,these grooves can be formed in its mass; but where a thin plate is usedthe groove or grooves are formed, as isindicated at (L3 (L3, by strikingup the surface of the flat portion a of the plate. As shown, two groovesare thus formed in the plate, the metal between them being bent upward,as indicated at (LU; but obviously both arms of the wire B could rest ina single groove (L3, and the second would then be unnecessary.

B is the wire bent so as to form a loop Z), with its ends b' b' broughttogether so as to enter the slot af, and their extreme ends enlarged, soas to prevent them from being drawn out of slot a2 longitudinally.Preferably heads b2 b2 are upset on the ends of the wire and passedthrough the opening a* or (U7; but if 110 such opening is provided theends may engage the inside of rim ct', and in that case it is sufficientto form the heads by bending the ends of the Wire, as is shown at U3 b3in Fig. 4.

O is the face-plate of my seal. Preferably I form it with a turned-uprim c' and a flat face c, and in all cases its depth with or without therim c' must be less than that of the rim or flange a' of plate A.

My device is put together by inserting the wire B in the flanged plateA, as described, then placing the face-plate O over it and within aflange a', and then turning down the top of the flange a/ over the edgeof faceplate O, as is indicated at (L7 in Figs. 1 and When theface-plate O has a rim c', the engagement of this rim-with theturned-down edge of the rim a' is more secure than where an unflangedface-plate, such as is shown in Fig. 4, is used.

I prefer to construet the plates A and C of sheet 1netal-such as tin-aswhere a seamsuch as is formed between the edges a' and c'-is made insuch material it is almost impossible to bend it vout and back again, asmight be done with lead. Any desired inscription can be stamped orwritten on the face c of plate C or on paper applied to this face.

lIavin g now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A seal consisting of a plate A, having a projectin g rim a' cut awayat (L2, in combination with a face-plate B, of less thickness than therim af, and a wire B, having a looped end b and legs b', with enlargedends, all substantially as and for the purpose speeified.

2. A Seal eonisting of a plate A, having a projecting rim a' out away ata, one'o'r more longitudinal grooves a3, and an opening in the rim atthe end of said grooves, in combination With face-plate B, of lessthiekness than the rim a', and a Wire B, having a looped end b and legsb', With enlarged ends, all substantially as and for the purposespecified. 3. A Seal consisting of a plate A, having a projeeting rim a'cut away at a2, in combination With a face-plate B, having a turned-nprim c' of less thiekness than the rirna', and a Wire B, having a loopedend b 'and legs b',

With enlarged ends, all substantially as and 25 for the pnrposespeoified.
